T-Gun F300 Cartridge Gun - Can be Fitted to Drill and Screw Guns - for Ø 1,96" - 10,48 fl oz cartridges

This worked incredibly well at delivering sealant in a controlled and smooth way. But I only managed a single use because I didn't read the instructions, as I rarely do in a hurry. My mistake. When you unwind the plunger using the drill, you will break the internal mechanism if you run it all the way back under power. Have just bought another, but next time I will wind back the final bit carefully by hand. Otherwise great.

This thing makes big caulking jobs so much easier, highly recommend.

The Tivoly t-gun supplied by Amazon does not have the steel reinforcement plate at front of machine. This means that the plastic frame can easily crack if too much pressure is applied e.g possible with viscous materials or if plunger hits end of tube. The drive gearing is plastic as well and it is highly geared so plunger moves too fast for precision work,even when pressing lightly on drill trigger. The model supplied is lightweight model probably F300 whereas the pictures look like they are mostly for the F450 heavier duty model. It is good for applying large quantities of softer sealants roughly e.g sealing between roof sheets or on coving. Could have been a decent gun if the plate was present and the gearing was lower. Contrary to at least one reviews the rod that pushes the plunger is actually blackened steel and not plastic.

Bought this to glue coving up but due to having carpal tunnel I was unable to squeeze the trigger on the gun. Well this solved that problem, it was brilliant.Yanno you see those videos of people using a 'fantastic tool' but when you order it and try to use it you are unable to replicate it...well not with this. See the video, that's exactly how easy it is to use it and exactly how to use it.This is invaluable for people who struggle to squeeze a trigger on a gun (caulking gun not pistol). I am going to be no-nails sticking stuff with ease now. Brilliant!

product works well, only two negatives....first the cost is very high & there is no way to relieve the pressure, you have to put the drill in reverse, or you waste loads of silicone.

Worked really well for injecting roof sealing mastic between sheets of roofing felt on a large shed.Roof too deep to climb onto and nail down the felt.The gun worked easily at arms length and effortlessly spread the sealant between the two layers of felt.Light and easy to use. Fitted my Makita combi drill really well. A very cost effective solution compared to bespoke cordless caulking guns.

Just amazing product

You need to be careful with this gadget. Make sure you read the instructions very carefully before use. NOT SUITABLE FOR ALL UK CARTRIDGES. No nonsense range for example from Screwfix will fit this without a problem, however Evostick gripfill will not as they are too long. Make sure you set the torque correctly on your drill, if it's set to max you will break this when the plunger reaches the end of it's travel as the tube holder is made of ABS and not reinforced at all.
